I do believe I FINALLY have it figured out. I wrote myself
the following how to. Please feel free to clean it up and
make it into an "Official CentOS 5 How To".
The only problem I have left is that the Guest XP can not
browse the Host's Samba server by SMB name (IP works fine)

T's CentOS 5 -- Virtual Box "Host Networking" bridge setup:
Note: a lot of this is taken from (with lots of refinements):
http://www.linuxweblog.com/virtualbox-host-networking
iptables: after creating br0 at etho's expense, you have to
change all references to "eth0" in your firewall
to "br0"
br0: will become the internal interface and have a "Fixed" (static)
IP address of 192.168.255.10
Support software (required);
"VBoxAddIF" from Virtual Basic
bridge-utils:
yum install bridge-utils
